Until 1970, only the dental hygienist was allowed to perform intraoral functions in all states. Although laws vary from state to state, virtually every state has modified, updated, and made changes to state restrictions to allow for the performance of intraoral procedures by all allied oral health care practitioners.

2. Silver paste was first mentioned as a restorative material for teeth by the:
a. Chinese
b. Greeks
c. Romans
d. French
ANS: A
Silver paste was first mentioned as a restorative material for teeth by the Chinese in 659 AD. More than 1000 years later, in 1800, it was produced in France from “shavings from silver cut from coins mixed with enough mercury to form a sloppy paste.” Health problems arising from the high mercury content of this early amalgam prompted the American Society of Dental Surgeons to pass a resolution in 1846 stating that amalgam should not be used under any circumstances.
